A new underwater battery storage technology is coming from Netherlands-based Ocean Grazer to address the issue of offshore long-duration storage. The company’s Ocean Battery is touted as innovative yet simple, based on existing technology, and capable of enhancing marine life along the way.

The investment is planned to support development and construction of Hydrostor’s 1.1GW, 8.7GWh of Advanced Compressed Air Energy Storage projects that are well underway in California and Australia, and help expand Hydrostor’s project development pipeline globally.

The completed acquisition of ClipperCreek launches Enphase Energy into the fast-growing market for electric vehicle charging systems.

Following approval from the Foreign Investment Review Board in November, the long-awaited sale of grid-operator Spark Infrastructure to a North American consortium led by private equity giant Kohlberg Kravis Roberts has been completed via a $5.2 billion “all-cash transaction”.

An agreement with Energy Vault may see resource company BHP stack 35-tonne blocks to store wind and solar energy in the Pilbara, northern Western Australia.

Brisbane-based flow battery company Redflow has completed its single biggest installation to date, a 2 MWh storage system in California for biowaste technology firm Anaergia.

The AI-enabled robot is claimed to ensure faster and more efficient deployment of solar modules in utility scale projects.

The transaction, for which Shell did not reveal the purchase price, will see the energy company pick up a U.S. project development pipeline which reportedly runs to more than 18 GW of solar generation and energy storage capacity across 26 states.

A U.S.-Israeli consortium is developing synchroinverters – inverters that mimic a synchronous generator and are able to actively respond to the grid’s frequency changes while stabilising the voltage. The new devices are expected to do this simultaneously and provide grid stability services in less than 16.67 milliseconds.

With Scottish company Smarter Grid Solutions having already seen its software deployed in the U.K., a pilot project in New York State has been a resounding success for a grid solution the NREL has predicted could unlock swathes of network capacity without the need for new power lines.
